LoadRunner function;
The parameters in the parameter array must all start with the same name, and are assigned values sequentially using underscores and numbers. The parameter array must have a parameter named _ count to record the length of the array.
1. Parameter type parameter type
File
Date/time
Group Name
Iteration number
Table
Unique id of unique number
Random Number of Random Number
Load generator name download generation name
User-Defined Function
Vuser ID: virtual user ID
XML
2. File storage location
Add column add Column
Add row add row
Delete column
Delete row
Edit with notepad use text editing
Data wizard is imported from ODBC through the database
Simulate parameter simulation parameters
3. Select column
By number
By name
4. File Format
Column delimiter comma delimiter tab tabulation delimiter space separator
First Data first data row
5. Select next row and select settings for the next row
Sequential values of sequential, which are assigned to vusers sequentially
Random random Value
Unique unique value
Same line as XX retrieves the same row of a parameter
6. Update value on time setting of update Value
Each iteration: update each iteration; indicates that the vuser uses a new value for each iteration of the script.
The value of each occurrence is updated each time. This indicates that the vuser uses the new value when each parameter appears.
Once is updated only once. This means that the vuser only updates the parameter value once during the running of the solution.
7. Value Setting after when out of value exceeds
Terminate the script when the abort vuser exceeds the limit.
When the number of continue in a cyclic manner exceeds the limit, return to the list header for another value.
Continue with last value use the last value in the parameter table
8. Assign virtual user values to allocate vuser values in the Controller
Automatically allocate block size: automatically allocates the block size.
Allocate XXX values for each vuser assigns XXX values to each virtual user
The above is a general explanation of the help document, and I will explain my thoughts:
1. Select next row
Is to select the next data method, sequential and random may occur when multiple users iterate the same data at the same time.
And unique won't.
2. Update value on time setting of update Value
Each iteration: update each iteration; indicates that the vuser uses a new value for each iteration of the script.
For a single user, each iteration is updated. for multiple users, each script is updated once.
The each occurrence value is updated each time. This indicates that the vuser uses the new value when each parameter appears. Note that if the lr_eval_string ("{ID}") parameter is used multiple times, this will be updated every time!
Once is updated only once. This means that the vuser only updates the parameter value once during the running of the solution.
